IC2800B310 contactors are used where time-delay opening of power circuits such as dc motor loads and resistor loads are required. They are normally open, single-pole contactors constructed with copper-jacketed coils which provide time delay on dropout. The contactors are front-connected and can be mounted on either insulating or noninsulating panels.

Normally Closed

Used to short-out resistance steps in starting dc motors. Contactors are normally closed, without blowouts, and are not designed to interrupt power.

Pick-up is instantaneous. Time-delay dropout results from use of a copper-jacketed coil and adjustment of this time delay is obtained by using a non-magnetic armature shim. Time delay of IC2800A501 contactors can be adjusted over a narrow range by the armature spring. Time delay of IC2800Y109 contactor can be adjusted over a wide range by a sliding shim.

Mount contactors on either metal or insulating panels. Make connections from the front.
